Application tiled March 2, 1912. Serial No. GLllO.

To' all iti/0m it may concern vl heretofore usedQand Q the ordinary drill- Be it known that- I, A.\izo1\" J. Booxr., a lieretoiore used, having a round shank 3 ycitizen of the United States, and a resident of Alniedia, in thecounty of Columbia 'and l State of Pennsylvania, have invented a new and Improved Beveled Drill-Socket, of

which the following is 'a full, clear, and exact description. This invention .relates to improvements in drill sockets, andl has for an object the provision of an improved. structure designed to receive the sha-nks of drills rcgardless of whether or not the same have tangs associated therewith.

'A further object of the invention is to provide a tapering socket formed square or irregular in cross sectionfor receiving a correspondingly shaped shank."-

vln carrying out. the'objeets of the invention, asocket is provided which mayy be square or hexagonal, or other similar shape. and which is beveled or tapered longitudinally so as to fit the usual taper of drill shanks.v A tang-receiving socket portion also provided which is designed to receive Athe usual tang. of the drill ift the same has ,not been broken 'o-i. lf the. tang has been broken off the lsocket will properly hold the drill after the shank thereot' has been squared. y

A practicalembodiment ,of the invention is represented in the accompanying drawingsforming apart of this specification. in which similar characters ot' reference indicate corresponding parts all the views.

Figure 1 is a longitudinal vertical section through a drill socket of the ordinalv con! struction having a round socket and a taligreceivingslot; Fig. 2 is a side view of a drill with the tang broken and with thev shank squared, the shank retaining its usualtapered shape; Fig. 3 is a side view ot the socket formed according to the present iuvention; Fig. 4 is a longitudinal vertical seetiontlirough the socket shown in- Figl 8. the drill disclosed in Fig 2 being fitted 4 onthe-line 5'-5 Referringpto the accompanying drawings by numerals, 1 indicates the. ordinaryv socket f and a tang 4. The shank l is adapted to fity into a tapering aperture in the socket niember l.

ln practical operation, the tang l often brMak-s and when this occurs the drill 2 of no further usefas the saine cannot ,be` held by the socket l.' By providing a socket 5 according' to the ,present invention, having a squared socket portion or bore 6, thc drill 9 may be properly fitted therein after 'being provided with squared portions 7. 'A

As clearly shown in Fig. 4the socket 5 by having'a bore 6 tapering similar to the b oie ."i of the structure shown in Fig. l, and also squared, as inoie clearly shown in Fig.

5, the same will firmly hold `the drill 2 against independent rotation.

l It will ot course be evident that the drill Q betore the tangv --l has been. broken, could lic used in a socket 5 by merely squaring the saine. :i notch .Q accomuiodating the tang. Bv this const ructiou ot' .socket the drill may be used either with or without the taiigai'id may be used to the-extreme limit of`tlie twisted part ot `the drillf.

ln vthe 4d ra wings the socket. 5 has been squared. but it will be evident that. hexag` lu testimony whereof I have signed 'my name to this specificationin the presence of two subscribing witnesses.
